Final answer:
Trip Flex allows customers to cancel their existing itinerary and receive a refund within a specified time period.
Step-by-step explanation:
Trip Flex, which is a feature offered by some airlines and travel agencies, allows customers to cancel their existing itinerary within a specified time period and receive a refund for their cancelled trip. The type of refund a customer receives depends on the terms and conditions of Trip Flex.
In most cases, a customer who cancels their trip with Trip Flex will receive a refund in the form of credit for future travel. This means that the customer can use the refunded amount to book a new trip with the same airline or travel agency.
However, it's important to note that the specific terms and conditions of Trip Flex may vary depending on the airline or travel agency. Some may offer refunds in the original form of payment, while others may not offer any refund at all.
